Solid‐phase backward extrusion of thermoplastics
Polymer Engineering & Science, 1982Abstract The backward extrusion process was studied as a means of forming projections and ribs on flat sections of thermoplastic parts. The simplified, open‐die axisymmetric and plane‐strain extrusion cases were mainly considered. The results were applied to the development of a continuous solid‐phase‐forming process. Commercial‐grade

Bubble Growth in Thermoplastic Foam Extrusion
Porous, Cellular and Microcellular Materials, 1998Abstract A condensed review will be presented regarding the bubble growth study. A modified model fitting to foam extrusion system will be discussed. The improved model focuses on the influence of blowing agent on bubble growth during thermoplastic foam extrusion.

Extrusion of thermoplastic elastomers in the solid state
Rheologica Acta, 1982The deformation in the solid state is a well known orientation process for polymers. An up-to-date account of developments in the production, structure, and properties of solid state extruded homopolymers can be found in [1]. Very recently, solid state extrusion has been applied for copolymers as well [2, 3]. Copolymers are extruded under lower forming

Process Design for Thermoplastic Foam Extrusion
2014Depending on the polymer used and the end-use application, thermoplastic foams are produced with densities ranging from 3% to 50% of the polymer density. Higher-density foams utilize chemical blowing agents (CBAs) that decompose to release gas that is dissolved in the melt.
